Chrysler Corporation engineers experimented with some off-the-wall intake manifolds in the late '50's, early '60's, like the ram induction two-4 barrel unit. It was a cross-ram with the left bank carburetor sitting above the right bank valve cover and the right bank carburetor sitting over the left bank valve cover. It was the longer runners that made the best power.

If I had to buy an intake manifold for you, it would be an Edelbrock 7164, Chevrolet Performance 12363420 or Professional Products 53001 (carb pad height 5.750")..
I bought the Edelbrock 7164, but according to Edelbrock, it's not much different than the one I had, the performer 2-0. It sits about 1/2" taller with the plenum about 1/2" further down than my old one.
Don't know if I'll end up with a 4 hole spacer or an open one.
